Abstract
Purpose: Retroperitoneal robotic-assisted pyeloplasty (ret-RAP) for ureteropelvic junction obstruction (UPJO) requires a larger retroperitoneal space (RS) to maintain specified distances between robotic (da Vinci) trocars and between trocars and the region of interest. A modified closed technique (MOT) and conventional closed technique (COT) were compared for creating an adequate RS with optical trocars. Methods: RS access in children with UPJO who underwent ret-RAP (n = 30) was MOT (n = 15) and COT (n = 15). All patients were positioned laterally. For MOT, a 5 mm optical trocar was inserted at the angle formed between the 12th rib and the erector spinae muscles. As the trocar was advanced under direct vision, it pierced the superficial subcutaneous layer, Scarpa's fascia, lumbar fascia, internal/external oblique and transversus abdominalis muscles, and the posterior renal fascia. Once in the RS, the tip of the scope was used for blunt dissection of perirenal fat, the tip was withdrawn until it was outside the perirenal fascia, and used to dissect toward the anterior abdomen in the pararenal fat layer. Results: Ages and weights at ret-RAP were similar (MOT: 5.6 ± 1.8 years versus COT: 7.8 ± 4.6 years; MOT: 20.6 ± 10.1 kg versus COT: 27.6 ± 13.9 kg). Times for RS access were similar (MOT: 1.6 ± 0.5 minutes versus COT: 1.9 ± 0.7 minutes), but RS expansion was significantly quicker in MOT (32.3 ± 8.7 minutes versus 52.0 ± 15.1 minutes; P < .001). Peritoneal injury caused carbon dioxide leakage in 4 of 15 COT cases and 0 of 15 MOT cases. Conclusion: RS expansion with MOT was safer because there were no peritoneal injuries and MOT was quicker than COT.

Abstract
Open and purely laparoscopic partial nephrectomy or heminephrectomy has been the standard management for renal duplication anomalies for symptomatic children with non-functional renal moieties. While robotic-assisted laparoscopic partial nephrectomy (RALPN) has been established as a safe and feasible option for the management of renal duplex anomalies, there remains a paucity of data on this topic. The aim of this study is to comprehensively review all available outcomes data and update the use of emerging technologies in robotic surgery which continue to make RALPN a viable and advantageous option in the management of renal duplex anomalies.

Abstract
The aim of this study was to compare outcomes of laparoscopic and robotic-assisted colectomy in children. All children who underwent a colectomy with a laparoscopic (LapC) or robotic-assisted (RobC) approach in our institution (January 2010-March 2023) were included. Demographics, surgical data, and post-operative outcomes within 30 days were collected. Additional cost related to the robotic approach was calculated. Comparisons were performed using Fisher tests for categorical variables and Mann-Whitney tests for continuous variables. A total of 55 colectomies were performed: 31 LapC and 24 RobC (median age: 14.9 years). Main indications included: inflammatory bowel disease (n = 36, 65%), familial adenomatous polyposis (n = 6, 11%), sigmoid volvulus (n = 5, 9%), chronic intestinal pseudo-obstruction (n = 3, 5%). LapC included 22 right, 4 left, and 5 total colectomies. RobC included 15 right, 4 left, and 5 total colectomies. Robotic-assisted surgery was associated with increased operative time (3 h vs 2.5 h, p = 0.02), with a median increase in operative time of 36 min. There were no conversions. Post-operative complications occurred in 35% of LapC and 38% of RobC (p = 0.99). Complications requiring treatment under general anesthesia (Clavien-Dindo 3) occurred in similar rates (23% in LapC vs 13% in RobC, p = 0.49). Length of hospitalization was 10 days in LapC and 8.5 days in RobC (p = 0.39). The robotic approach was associated with a median additional cost of 2156€ per surgery. Robotic-assisted colectomy is as safe and feasible as laparoscopic colectomy in children, with similar complication rates but increased operative times and cost.

Abstract
The field of plastic surgery remains at the forefront of technological and surgical innovation. However, the promising applications of robotics in plastic surgery must be thoughtfully balanced with hospital finances and reimbursements. Robotic systems have been studied extensively across multiple surgical disciplines and across diverse health care systems. The results show that there may be equal or better patient outcomes than alternatives. In an era where fiscal responsibility in health care is a top priority, thoughtful budgeting and spending must be considered and revisited frequently to attain sustainable organizational models that ensure appropriate use of robotic technology.

Abstract
BACKGROUND The selection of best surgical approach for treatment of vesico-ureteral reflux (VUR) in the pediatric population remains debated. This study aimed to report the results of a multicenter survey about the current trends in surgical management of pediatric VUR. METHODS An online questionnaire-based survey was performed, with participation of six international institutions. All children (age <18 years) affected by primary III-V grade VUR, who were operated over the last 5 years, were included. The incidence of each VUR intervention, patients' demographics and outcomes were analyzed. RESULTS A total of 552 patients (331 girls), with a median age of 4.6 years (range 0.5-17.6), were included. Deflux® injection (STING) was the most common technique (70.1%). The multicenter success rate after single treatment was significantly lower after STING (74.4%) compared with the other treatments (P=0.001). Persistent VUR rate was significantly higher after STING (10.8%) compared with the other treatments (P=0.03). Choosing endoscopy over surgery mean reducing Clavien Dindo grade 2 complications by 5% but increasing redo procedure rate by 7%. STING was the most cost-effective option. CONCLUSIONS This survey confirmed that the choice of the technique remains based on surgeon's preference. Deflux® injection currently represents the first line therapy for primary VUR in children and the role of surgical ureteral reimplantation is significantly reduced. STING reported acceptable success rate, less postoperative complications and lower costs but higher failure and re-operation rates and related costs compared with the other surgical approaches. The adoption of laparoscopy and robotics over open reimplantation remains still limited.

Retrograde stent with external string for pediatric robotic pyeloplasty: does it reduce cost and complications? J Robot Surg 2023; 17:185-189. [PMID: 35488080 DOI: 10.1007/s11701-022-01411-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 03/27/2022] [Indexed: 10/18/2022]
Abstract
Robotic-assisted pyeloplasty (RAP) is a mainstay in the treatment of ureteropelvic junction obstruction (UPJO) in children. At our institution, to limit planned operating rooms visits we have placed a ureteral stent with an external string (SWES) immediately prior to RAP. In this study, we sought to quantify the operative time, complications, and costs associated with this approach compared to the traditional approach, requiring subsequent stent removal in the operating room. We hypothesized the SWES cohort would have decreased cost, yet with similar operative time and complications. We retrospectively collected all RAPs performed at our institution using the SWES approach (Aug 2012-July 2017). We excluded those with a redo pyeloplasty, and/or a percutaneous nephrostomy tube for post-operative drainage. We collected 30-day costs linked to the patients' MRN using the Pediatric Health Information System (PHIS) database. We compared 30-day healthare costs for all patients following RAP. We compared our SWES group to a national cohort of all pediatric RAP during the same time period. Lastly, we sent an anonymous, electronic survey to urologists of all PHIS institutions to identify the predominant postoperative drainage, nationally. Within our institution, we reviewed all those treated with SWES (n = 85) (Table 1). The median 30-day cost was $10,548 among those with SWES (Table 2). This was significantly less than the overall, national cohort of all pediatric RAP during the same period ($14,119, p < 0.001). There was a 15.5 % rate of unplanned return to the hospital in the SWES group. Of those unplanned returns, 8.2 % (7/85) had unplanned return for a procedure (3 for unplanned stent removal, 2 for nephrostomy tube for persistent obstruction, 1 for omental hernia, and 1 for stent replacement). With a 42.5 % (37/87) response rate, our nationwide survey found 84.6 % primarily leave stents WITHOUT a string, 7.7 % left nephrostomy tubes, and 7.7 % stents with strings. During pediatric RAP, placement of a SWES takes little time, carries a risk of unplanned visit to the operating room, saves the patient a certain, second anesthetic for stent removal, and amounts to a cost savings of approximately 25 %.

Abstract
Incisions in the supra-pubic region have been described robotic-assisted surgery to improve cosmetic results in adults, but seldom in children. We aimed to present an innovative trocar placement in the Pfannenstiel line, named Scarless Laparoscopic Incisions in Pfannenstiel (SLIP), and evaluate its feasibility for various intra-abdominal procedures and its cosmetic results in pediatric robotic surgery. We performed a monocentric prospective study, including children undergoing robotic-assisted surgeries using a SLIP approach (July 2019-September 2021). Data regarding demographics, surgery, and outcome were collected and reported as median (range), or number (percentage). Cosmetic results were evaluated with a questionnaire. A SLIP approach was performed in 50 children (24 cholecystectomies, 12 splenectomies, 2 cholecystectomies and splenectomies, 9 colonic resections, 2 choledochal cyst resections, and 1 pancreatic pseudocyst resection). Median age was 11 years (2-18) and median weight 35 kg (10.5-80). Conversion to laparoscopy occurred in two cases. Post-operative complications occurred in 5 patients (10%), after colectomies [intrabdominal abscess (n = 3), stoma dysfunction (n = 1), parietal abscess (n = 1)], of which 3 (6%) required reintervention (intrabdominal abscess n = 2, stoma dysfunction n = 1). Regarding scars, 68% (n = 28) of parents and patients reported the maximal score of 5/5 for global satisfaction and 63% (n = 26) had all scars hidden by underwear. SLIP approach is versatile and can be used in supra- and infra-mesocolic robotic-assisted procedures. The low complication rate shows its safety in both young children and teenagers and does not increase operative difficulties. It results in high patient satisfaction regarding scars, and a scarless abdomen.

Abstract
Robot-assisted laparoscopic extravesical ureteral reimplantation (RALUR) and robotic ureteroureterostomy (RUU) are two mini-invasive surgical techniques that have begun to be performed in pediatric urology in recent years. RALUR has been employed especially for VUR treatment, while RUU is considered principally in case of complex doubled ureteral systems. Our aim is to discuss the safety and feasibility of these approaches in children, focusing on technical considerations and supporting their use in different anomalies and pathologies of the ureterovesical junction. We retrospectively collected data about 58 patients who underwent 44 dismembered RALUR (D-RALUR), 28 non-dismembered RALUR (ND-RALUR) and 5 RUU between May 2020 and December 2021. Indications for surgery were primary or secondary vesicoureteral reflux, megaureter, secondary UVJ obstructions, complicated doubled ureteral systems. Mean age was 3.5 years (range 0.6-12.9) and mean weight 17.1 (range 7.2-80). No intraoperative complications occurred nor conversion to open approach were reported. Major postoperative complications were reported in 11.7% of cases with a higher incidence for ND-RALUR. Mean hospital stay was 2.14 days (range 1-8). Success rate at the short-term follow-up was 91.9% for D-RALUR, 96.3% for ND-RALUR and 100% for RUU. RALUR and RUU are two feasible and safe procedures to perform in children. RALUR represents the most required and adequate technique in the treatment of UVJ pathologies, however, in selected cases RUU could represent an effective alternative that has to be considered.

Abstract
INTRODUCTION Robot-assisted laparoscopic (RAL) urologic surgery is widely used in pediatric patients, though less commonly in infants. There are small series demonstrating safety and efficacy in infants, however, stratification by infant size has rarely been reported. Whether a cut-off weight, below which RAL surgery is not technically feasible, safe, or efficacious has not be determined. OBJECTIVE To assess safety and efficacy of RAL urologic procedures in infants <1 year of age, weighing ≤10 kg. STUDY DESIGN A single-institution retrospective cohort study of patients <1 year of age, and ≤10 kg undergoing RAL pyeloplasty (RALP) or RAL ipsilateral ureteroureterostomy (RALUU) between January 2011 and September 2020 was performed. Demographic, operative, and post-operative data were extracted from the medical record. Patients were stratified by post-hoc weight quartiles. Outcomes, including operative time, total OR time, estimated blood loss (EBL), post-operative length of stay (LOS), post-operative radiographic improvement, and 30-day complications were assessed by weight quartile for each procedure. The Kruskal-Wallis rank test was used to assess differences in continuous outcomes between weight quartiles and Pearson's Chi-squared test was used for categorical outcomes. RESULTS Of 696 RAL urologic surgeries performed, 101 met eligibility criteria. Median (IQR) age of patients was 7.2 (6.0-9.2) months with median weight of 8.0 (7.2-8.9) kg. The lowest weight was 5.5 kg. Procedures performed included 79 RALPs (78.2%), 22 RALUUs (21.8%). We identified 97 patients (94%) with post-operative imaging, with radiographic improvement in 92%. When stratified by weight quartile, there was no difference between groups in median operative time, total OR time, LOS, EBL, or post-operative radiographic improvement for both RALP and RALUU. Post-operative complications were assessed based on Clavien-Dindo classification with the majority of complications (9/12, 75%) in the >50th percentile weight groups. DISCUSSION To our knowledge, this is the largest published series of infant RAL urologic procedures, with similar rates of radiographic improvement and post-operative complications to prior published series. There are few prior series of RALP and RALUU in infants ≤10 kg, and we show comparable outcomes regardless of patient weight. Our study is limited by the inherent biases of retrospective studies. CONCLUSION RAL urologic surgery is technically feasible, safe, and efficacious in infants ≤10 kg, without worse outcomes as weight decrease. A cut-off weight, below which RAL surgery should not be performed has yet to be identified.

[PMID: 34886244 PMCID: PMC8657248 DOI: 10.3390/ijerph182312519] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Revised: 11/24/2021] [Accepted: 11/25/2021] [Indexed: 11/17/2022]
Abstract
(1) Background: The goal of the paper was to establish the factors that influence how people feel about having a medical operation performed on them by a robot. (2) Methods: Data were obtained from a 2017 Flash Eurobarometer (number 460) of the European Commission with 27,901 citizens aged 15 years and over in the 28 countries of the European Union. Logistic regression (odds ratios, OR) to model the predictors of trust in robot-assisted surgery was calculated through motivational factors, using experience and sociodemographic independent variables. (3) Results: The results obtained indicate that, as the experience of using robots increases, the predictive coefficients related to information, attitude, and perception of robots become more negative. Furthermore, sociodemographic variables played an important predictive role. The effect of experience on trust in robots for surgical interventions was greater among men, people between 40 and 54 years old, and those with higher educational levels. (4) Conclusions: The results show that trust in robots goes beyond rational decision-making, since the final decision about whether it should be a robot that performs a complex procedure like a surgical intervention depends almost exclusively on the patient’s wishes.

Comparative analysis of robotic-assisted versus laparoscopic cholecystectomy in pediatric patients. J Pediatr Surg 2021; 56:1876-1880. [PMID: 33276970 DOI: 10.1016/j.jpedsurg.2020.11.013] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 11/03/2020] [Accepted: 11/14/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND Despite increased utilization of robotic-assisted surgery in the pediatric population during the past decade, reports of comparative analysis between robotic surgery and laparoscopic surgery are lacking. Our aim was to evaluate outcomes between pediatric robotic-assisted cholecystectomy (RC) and laparoscopic cholecystectomy (LC). METHODS A single institution retrospective analysis of 299 patients undergoing either RC or LC, between January 2015 and December 2018 was performed. Demographic data as well as clinical characteristics and related outcomes were abstracted and compared using univariate analysis. Related hospital costs were estimated using a charge to cost methodology. RESULTS The median age of the cohort was 15.5 years (IQR 14.0-17.0); 76% females and 70% white, with 74% (n = 220) undergoing LC and 26% (n = 79) undergoing RC. The majority of RC were performed using single-site technique and RC proportion increased with time (10% in 2015 vs. 41% in 2018, p<0.001). The majority of RC were more commonly attributed to patients with nonacute indications for cholecystectomy compared to acute clinical indications (87% vs. 13%). Median operative time was 98 min vs. 79 min for RC and LC respectively (p<0.001). Median postoperative LOS was similar between groups (22 h). There were no significant differences in postoperative complication, in-hospital opioid utilization and 30-day readmissions. Average total hospital costs for RC were $15,519 compared to $11,197 for LC. CONCLUSIONS Pediatric robotic-assisted cholecystectomy is feasible with similar outcomes compared to laparoscopic cholecystectomy. However, it is associated with longer operative times and higher costs. The single-site RC technique may provide a potential cosmetic benefit.

Open versus minimally-invasive surgical techniques in pediatric renal tumors: A population-level analysis of in-hospital outcomes. J Pediatr Urol 2021; 17:534.e1-534.e7. [PMID: 33849794 PMCID: PMC8449787 DOI: 10.1016/j.jpurol.2021.03.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2020] [Revised: 01/31/2021] [Accepted: 03/11/2021] [Indexed: 02/06/2023]
Abstract
INTRODUCTION Minimally-invasive surgery (MIS) has been adopted slowly in pediatric oncology. We attempted to describe contemporary national trends in MIS use; we hypothesized that adolescents (who are more likely to have relatively small renal cell carcinomas) would have a higher proportion of MIS than younger children (who are more likely to have relatively large Wilms tumors) and that this relationship would vary by region. OBJECTIVE To explore whether pediatric urologic oncology outcomes vary by patient age or by surgical technique. METHODS We queried the 1998-2014 National Inpatient Sample (NIS) and included encounters in children aged ≤ 18 y, ICD-9 diagnostic code for renal tumor, and procedure code for open or MIS partial or radical nephrectomy. All analyses used weighted descriptive statistics and outcomes are compared based on age group (</>10 y) or surgery type; Wald-Chi square test was used for differences in proportions and unadjusted weighted ANOVA was used to test for differences in means. RESULTS 9259 weighted encounters were included; 91% were <10 years old and 50.7% were female. MIS surgery accounted for 1.8% of encounters; there was a difference in proportions by age group (1% <9 y vs. 9.9% >9 y, p < 0.01). The proportion of surgery type was similar across regions within age groups, however. Complications occurred in 13.3% of encounters; mean inpatient length of stay was 8.9 days (SD: 0.3); mean cost was $ 34,457.68 (SD: $1197.00). There was no evidence of a difference between surgery type and proportion of post-operative complications, mean inpatient length of stay or mean inpatient cost. DISCUSSION The admission-based, retrospective design of NIS left us unable to assess long-term outcomes, repeated admissions, or to track a particular patient across time; this is particularly relevant for oncologic variables on interest such as tumor stage or event-free survival. We were similarly limited in evaluating the effect of pre-surgical referral patterns on patient distributions. CONCLUSION In this preliminary descriptive analysis, MIS techniques were infrequently used in children, but there was a higher proportion of MIS use among adolescents. There were similar proportions of surgery type across geographic regions within the United States. Whether this infrequent usage is appropriate is as yet unclear given the lack of Level I evidence regarding the relative merits of MIS and open surgery for pediatric and adolescent renal tumors.

Robotic upper tract surgery in infants 6 months or less: is there enough space? J Robot Surg 2021; 16:193-197.

Abstract
Robot-assisted laparoscopic surgery (RALS) has recently been described in children < 1 year old. However, little data exist on robotic utilization in infants ≤ 6 months old, likely due to concerns for limited intraabdominal space and decreased distance between ports in this cohort. We hypothesized that the robotic approach can be successfully used for infants ≤ 6 months old. A prospectively collected database of patients undergoing urologic robotic surgery at our institution was reviewed. Patients ≤ 6 months and ≥ 4 kg were included. Patient demographics, intraoperative details, hospital length of stay, and complications were reviewed. Descriptive statistics were performed. Twelve patients ≤ 6 months old underwent urologic robotic surgery by three surgeons at our institution (2013-2019): pyeloplasty (6), ureteroureterostomy (4), heminephrectomy (1), and nephrectomy (1). Median age at surgery was 4.75 months (IQR 4, 6). Median weight was 7.09 kg (IQR 6.33, 7.78). Median console time was 105 min (IQR 86, 123). For all procedures, 8-mm robotic arm ports were used. No procedures were converted to open. Median post-operative hospital stay was 24 h (IQR). Febrile UTI was the only complication occurring within 30 days of surgery (n = 4, 33%; 7-20 days, Clavien grade 2). For those undergoing pyeloplasty or ureteroureterostomy (n = 10), postoperative ultrasound showed improved (n = 9) or stable hydronephrosis (n = 1). At a median follow-up of 19.73 months (IQR 4.27, 38.32), no patient required an unplanned secondary intervention. Robotic upper urinary tract surgery is feasible and safe in patients ≤ 6 months of age and can be performed successfully with the same technique as for older children.

Abstract
Almost 30 years have passed since the inception of minimally invasive surgery in urology and specifically in pediatric urology. Laparoscopy has now become an essential tool in the pediatric urologic armamentarium. The application of robot-assisted surgery in pediatrics has allowed for widespread utilization for common reconstructive procedures such as pyeloplasty and ureteral reimplantation. Understanding the implementation, technical considerations, and outcomes are critical for continued success and adoption. This has allowed for increased use in more complex urologic procedures such as redo pyeloplasty, dismembered ureteral reimplantation, catheterizable channel creation, and bladder augmentation.

Time-Driven activity-based costing identifies opportunities for process efficiency and cost optimization for robot-assisted laparoscopic pyeloplasty. J Pediatr Urol 2020; 16:460.e1-460.e10. [PMID: 32605871 DOI: 10.1016/j.jpurol.2020.05.146] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Revised: 04/18/2020] [Accepted: 05/14/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND Robot-assisted laparoscopic pyeloplasty (RALP) is a commonly performed procedure in children, but its actual cost implications on the healthcare ecosystem have not been adequately defined. Time-driven activity-based costing (TDABC) is a novel cost accounting method derived from value based healthcare systems that may offer one pathway to assess institutional costs. OBJECTIVE To determine the true cost of a robot-assisted laparoscopic pyeloplasty (RALP) in the pediatric population using TDABC, and compare it to traditional cost accounting. And to utilize TDABC to minimize cost and improve time-flow efficiency. SUBJECTS/PATIENTS AND METHODS The RALP care pathway was defined from patient arrival to the pre-operative suite to discharge from the post-anesthesia care unit (PACU). Process maps were created with an interdisciplinary team to survey RALP activities. Retrospective time stamps were obtained from the electronic medical record for fiscal year 2016 (FY16) RALP cases, and were validated by prospectively stopwatch timing additional RALP cases. Male and female pediatric patients undergoing a unilateral RALP during FY16 and during the prospective study period (June 2017-October 2017) were included. Procedure costs were calculated using TDABC after determining the capacity cost rate for all personnel and assets, and multiplying them with the time stamps. RESULTS 25 RALP cases were analyzed for FY16. TDABC determined a total cost of $15 319/case, when direct, indirect and capital robot cost are included. Traditional cost accounting amounted to a total of $16 158/case. The current robot utilization rate is 22% of total capacity, effectively increasing the total RALP cost by 16%. Time stamps with the most variance were pre-operative services (115 ± 27.5 min), robotic console (142 min ±30.7 min) and PACU times (145 ± 101.1 min) (Figure) DISCUSSION: This study represents the first TDABC implementation in robot-assisted pediatric procedures. Previous TDABC in other areas of urology similarly revealed discrepancies between traditional cost accounting and TDABC. The present study demonstrates a higher total cost than previous cost accounting studies for the RALP, however, this is the first effort to include indirect costs in the final calculations. This study does convey the limitations of a retrospective analysis and those inherent to a single institution study. CONCLUSION TDABC defined the magnitude of cost variation based on robot utilization of a RALP. Traditional cost accounting overestimates the actual costs of a RALP. TDABC also identified high-cost and high variability loci in the RALP process map that will be targeted for process and quality improvement while further reducing assessed costs.

Abstract
Abstract
Background
There is a lack of evidence on the surgical approach for children and adolescents undergoing cholecystectomy. Therefore, the aim of this systematic review is to compare the safety and efficacy of minimally invasive cholecystectomy to open cholecystectomy in children and/or adolescents.
Main body
A search was conducted on MEDLINE, PubMed, Cochrane and Embase from inception to October 2018. We included comparative studies investigating outcomes following robotic-assisted, laparoscopic and/or open cholecystectomy in children and/or adolescents. The outcomes of interest included post-operative complication rate, operation time, length of hospital stay, post-operative pain and conversion to open procedure. The Newcastle-Ottawa Scale was used to assess the risk of bias. Meta-analysis was performed using random-effect models.
Twenty-one studies were included involving 927 children and/or adolescents. All, but one, compared outcomes between laparoscopic versus open cholecystectomy. The great majority of the included studies presented a low risk of bias. Patients undergoing laparoscopic cholecystectomy had less post-operative complications (RR: 0.57; 95%CI 0.35 to 0.94), reduced length of hospital stay (MD − 3.73; 95%CI − 4.88 to − 2.59), but longer operative time (MD 26.61; 95%CI 9.35 to 43.86) when compared to open cholecystectomy. The average conversion from laparoscopic to open cholecystectomy was 7% across studies.
Conclusions
The current evidence suggested that laparoscopic cholecystectomy in children and/or adolescents is safe resulting in lower rates of postoperative complications and length of stay, but longer operative times, when compared to the open approach.

Abstract
Background: Three-dimensional (3D) laparoscopic surgery in pediatrics is still uncommon and few studies assessed in clinical practice advantages and disadvantages. Applicability and effectiveness of 3D versus two-dimensional (2D) laparoscopic procedures in congenital and acquired conditions in children are still unknown. We assessed applicability and effectiveness of 3D compared with 2D laparoscopic procedures in a pediatric setting. Methods: Two groups of patients who underwent 3D or 2D laparoscopic surgical procedures between May 2016 and April 2018 were compared. Each 3D/2D laparoscopic procedure was assessed with a surgeon/assistant questionnaire. Results: The 3D group included 30 patients and the 2D group 32 patients. The analysis of the 3D/2D questionnaire showed statistically significant superiority of 3D technical aspects (P = .0000), allowing a better spatial orientation and depth perception, reducing manipulation and trauma to tissues. Moreover, no difference was reported in physical complaints (P = .7084), but decreased visual fatigue was highlighted by surgeon (P = .000). Conclusions: In pediatric patients, 3D laparoscopic procedures prove to be more effective facilitating the surgeon's performance, while maintaining the benefits of minimally invasive surgery.

Abstract
Background and Objectives: Robotic surgery is currently at the forefront of both adult and pediatric treatment. The main limit in the wide adoption of this technology is the high cost of purchasing and running the robotic system. This report will focus on the costs assessment of running a robotic program in a pediatric surgery center in Romania. Materials and Methods: In 12 months we performed 40 robot-assisted procedures in children. We recorded and analyzed data regarding their age, gender, pathological condition and comorbidities, surgical procedure, time of surgery, complications, hospital stay and related costs, medication, robotic instruments and consumables, additional cost, and income per case received from the National Insurance Company (NIC). Results: Mean cost per case was €3260.63 (€1880.07 to €9851.78) and was influenced by type of the procedure, intraoperative incidents, postoperative complication, and non-scheduled reinterventions (p < 0.05). The direct costs for operating the surgical robot were relatively constant, regardless of the surgical procedure (mean €1579.81). The reimbursement from the NIC ranged from 5% to 56% (mean 16.9%) of the total cost per case. Conclusion: In Romania, a pediatric surgery robotic program is not cost-efficient and cannot operate relying solely onto the health insurance system.

Abstract
BACKGROUND/PURPOSE Payers have established unplanned returns as quality measures tied to reimbursement. We sought to identify patient characteristics and surgical factors associated with unplanned returns and postoperative complications following intraabdominal pediatric urologic procedures. Only one study has emergency room visits in pediatric urology, but included only limited case complexity. METHODS We retrospectively reviewed electronic medical records of all pediatric patients who underwent urological surgery from 2007 to 2016 by a single surgeon. Univariate and multivariate regressions were used to determine factors associated with length of stay, unplanned ER visits and readmissions. RESULTS A total of 372 cases were included, of which 251 were robotic and 121 were open. Overall, the rate of ER visits was 19%, rate of readmissions was 8.7%, and rate of reoperations was 4.3%. We found that the odds of a urologic ER visit and Clavien grade II (infectious) complications were comparatively lower for robotic surgery, but not readmission. Undergoing a lower tract procedure was significantly associated with a related ER visit; however, patient insurance status was not related to unplanned returns. CONCLUSIONS Procedure characteristics, not patient demographics were associated with unplanned returns. Robotic approach was associated with fewer ER visits and infectious complications, indicating potential cost savings. LEVELS OF EVIDENCE Level 3 Treatment Study.

Abstract
INTRODUCTION Open pyeloplasty (OP) has traditionally been the standard for the operative management of ureteropelvic junction obstruction in children. With advances in minimally invasive pyeloplasty (MIP) techniques, it is quickly becoming a popular alternative in both adult and pediatric population. OBJECTIVE To evaluate the differences in outcomes between MIP and OP for the surgical correction of ureteropelvic junction obstruction in children. STUDY DESIGN Data were obtained from the pediatric National Surgical Quality Improvement Program 2012-2017. We identified 1280 patients who underwent MIP and 1190 patients who underwent OP between 2012 and 2017. Propensity score matching was utilized to adjust for baseline differences. Univariate and multivariable regression were performed to assess odds of complications and procedure-related readmission. RESULTS Patients who underwent OP had a significantly decreased operative time (192.42 vs 142.00 min, p < 0.001) compared to MIP. There was no significant difference in the rates of overall peri-operative complications (3.7% [MIP] vs 2.4% [OP] p = 0.397). On multivariable analysis, patients undergoing OP had a lower risk of procedure-related readmission (odds ratio [OR] 0.404, 95% confidence interval [CI] 0.157-0.951, p = 0.046) than MIP. In a multivariable linear regression model, the risk of having any postoperative complication, regardless of surgical approach, decreased with increasing patient age (OR 0.945, 95% CI 0.893-0.996, p = 0.037). DISCUSSION Although recent small, retrospective institutional studies have found decreased hospitalization time of MIP as compared to OP, in our large prospective database, we found no such association. While some studies suggest a higher rate of wound complications in the OP group, this was not reproduced in our study as well. MIP was, in fact, associated with higher rate of readmissions as compared to the OP group, which may act as a surrogate of long-term complications in these patients. CONCLUSION MIP offers an alternative to OP in the pediatric population with similar rates of peri-operative complications. However, our study shows decreased odds of procedure-related readmission in OP, which may serve as a surrogate for less postoperative complications in these patients.

Robot-assisted laparoscopic ureteral reimplantation in children: a valuable alternative to open surgery. World J Urol 2019; 38:1849-1854. [PMID: 31004205 DOI: 10.1007/s00345-019-02766-y] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2018] [Accepted: 04/09/2019] [Indexed: 12/25/2022] Open
Abstract
INTRODUCTION Robot-assisted laparoscopic surgical systems have led to new minimally invasive options for complex reconstructive procedures in children including for vesicoureteral reflux (VUR). Robot-assisted laparoscopic ureteral reimplantation has been shown to be a viable minimally invasive surgical option for children with VUR. However, higher-than-expected complication rates and sub-optimal reflux resolution rates at some centers have also been reported. METHODS This article provides a focused literature review as well as current perspectives on open reimplantation and robot-assisted laparoscopic ureteral reimplantation as non-endoscopic surgical options for pediatric VUR. RESULTS The heterogeneity of surgical outcomes may, in part, be due to the learning curve inherent with all new technology and procedures. As a result, the current gold standard surgical option for VUR continues to be open ureteral reimplantation. While it remains to be seen if robot-assisted laparoscopic surgery will gradually replace open surgery as the most utilized surgical option for VUR in pediatric patients, robot-assisted laparoscopic ureteral reimplantation with the current robotic surgical systems may be just one step toward an eventual minimally invasive option that all experienced surgeons can offer with the requisite high success rates and low major complication rates. CONCLUSION Robot-assisted laparoscopic ureteral reimplantation remains a viable minimally invasive surgical option for children with VUR, but with the expected learning curve associated with all new technologies.

Abstract
Introduction: Robotic assisted surgery (RAS) is one of the most recent surgical approaches that has quickly been adopted by the pediatric urology community. Over the last decade, a vast amount of manuscripts has been published, supporting the safety and applicability of RAS in the pediatric population. The quality of published literature about this innovative technology remains supported by case-reports and retrospective case-series. Historical behavior of literature productivity and implementation of laparoscopy followed a similar trend. We present the historical publication uptake of RAS in pediatric urology and other surgical disciplines using a bibliometric comparison of the most cited manuscripts. Materials and Methods: A systematic search and review of the literature was undertaken by the authors. Literature search was performed in OVID, PubMed, EMBASE, Scopus, Web of Science, and Google Scholar. The search period included all publications between 1985 and June 2018. All languages were included. Data analysis for graphical representation was performed using VOSviewer® version 1.6.8 and Impact Index Analysis was used to adjust the citations by the time since publication. Results: A total of 1,014 titles were identified. After applying exclusion criteria, 200 papers were included for the RAS arm and 402 for the laparoscopic one. Case-series was the most common type of publication. Average citations for laparoscopic manuscripts was 23 (SD ± 31) and for RAS was 20 (SD ± 31.5). The impact index analysis showed an average of 95 (SD ± 167) for laparoscopic manuscripts vs. 66 (SD ± 101) for RAS. The laparoscopic manuscript with the highest citation count had 199 citations with an impact index of 12.1. And the RAS manuscript with the highest citation count had 280 citations and an impact index of 4.3. Conclusion: Literature productivity in pediatric laparoscopic and RAS has quickly grown. Pediatric Urologists play a key role in the introduction of this innovative tool. Literature supporting its implementation and future consolidation requires to focus on increasing the level of evidence.

Abstract
Current management of vesicoureteral reflux (VUR) in children is the result of a steady albeit controversial evolution of data and thinking related to the clinical impact of VUR and urinary tract infection (UTI) in children, the value of clinical screening, and the relative impact of testing and interventions for VUR. While controversy continues, there is consensus on the importance of bladder dysfunction on VUR outcomes, the likelihood of VUR resolution, and the fact that not all children with VUR require active treatment. Early efforts to define risk stratification hold the most promise to provide more patient-specific treatment of UTI and VUR in children.

Abstract
Pediatric robotic-assisted laparoscopic procedures are becoming increasingly common. They have been shown to be safe in younger patients, including infants. Successful adoption of robotic-assisted surgery in infants requires an understanding of the technical factors unique to this patient population. This review will delineate the specific considerations to safely perform robotic-assisted laparoscopic procedures in infants, including physiological changes associated with pneumoperitoneum in infants, positioning, trocar placement, and docking.

Abstract
The evolution of robotic surgical technology and its application in Pediatric Urology have been rapid and essentially successful. Further development remains limited in three key areas: procedural inefficiencies, cost and integration of surgical and clinical information. By addressing these challenges through technology and novel surgical paradigms, the real potential of surgical robotics in pediatric, as well as adult applications, may ultimately be realized. With this evolution, a continued focus on patient-centered outcomes will be essential to provide optimal guidance to technical innovations.

Abstract
BACKGROUND Since the late 1980s, minimally invasive surgery (MIS) has been one of the fastest growing approaches for surgical procedures. However, its development has reached a plateau. One of the reasons is the difficulty to operate on more complex cases, such as neonatal procedures. Some experts report outstanding outcomes for complex operations, but not all surgeons may be able to achieve the same results. Is robotic surgery (RS) a solution? METHODS To answer this question, we reviewed the current indications of RS for the pediatric population and the steps needed to incorporate the robotic surgical system in a children's hospital. We reported our experience and presented our first results and the encountered problems. RESULTS After a year and a half of experience with RS, several lessons were learned: (1) the current robotic surgical system cannot yet be considered a replacement to conventional MIS, (2) docking is less time consuming than expected, (3) postoperative pain is significantly decreased, (4) the absence of haptic feedback is still a matter of concern, and (5) costs can be afforded by sharing the RS with adult surgeons. CONCLUSIONS Based on our experience, the advantages seem to outweigh the drawbacks as it encourages team building and increases overall comfort for the surgeon. However, the current literature fails to prove that RS gives better results for pediatric patients. New advances in technology will probably help to overcome the encountered difficulties and the high costs.

Abstract
INTRODUCTION Since 2010, there have been few new data comparing perioperative outcomes and cost between open (OP) and robotic pyeloplasty (RP). In a post-adoption era, the value of RP may be converging with that of OP. OBJECTIVE To 1) characterize national trends in pyeloplasty utilization through 2015, 2) compare adjusted outcomes and median costs between OP and RP, and 3) determine the primary cost drivers for each procedure. STUDY DESIGN We performed a retrospective cohort study using the Premier database, which provides a nationally representative sample of U.S. hospitalizations between 2003 and 2015. ICD9 codes and itemized billing were used to abstract our cohorts. Trends in utilization and cost were calculated and then stratified by age. We used propensity scores to weight our cohorts and then applied regression models to measure differences in the probability of prolonged operative time (pOT), prolonged length of stay (pLOS), complications, and cost. RESULTS During the study period 11,899 pyeloplasties were performed: 75% open, 10% laparoscopic, and 15% robotic. The total number of pyeloplasty cases decreased by 7% annually; OP decreased by a rate of 10% while RP grew by 29% annually. In 2015, RP accounted for 40% of cases. The largest growth in RPs was among children and adolescents. The average annual rate of change in cost for RP and OP was near stagnant: -0.5% for open and -0.2% for robotic. The summary table provides results from our regression analyses. RP conferred an increased likelihood of pOT, but a reduced likelihood of pLOS. The odds of complications were equivalent. RP was associated with a significantly higher median cost, but the absolute difference per case was $1060. DISCUSSION Despite advantages in room and board costs for RP, we found that the cost of equipment and OR time continue to make it more expensive. Although the absolute difference may be nominal, we likely underestimate the true cost because we did not capture amortization, hidden or down-stream costs. In addition, we did not measure patient satisfaction and pain control, which may provide the non-monetary data needed for comparative value. CONCLUSION Despite an overall decline in pyeloplasties, RP utilization continues to increase. There has been little change in cost over time, and RP remains more expensive because of equipment and OR costs. The robotic approach confers a reduced likelihood of pLOS, but an increased likelihood of pOT. Complication rates are low and similar in each cohort.

Abstract
PURPOSE OF REVIEW Although open ureteral reimplantation remains the gold standard for surgical correction of vesicoureteral reflux (VUR), robotic-assisted laparoscopic ureteral reimplantation (RALUR) holds promise and is becoming more widely utilized. The present article outlines primary operative techniques for RALUR, summarizes the current literature with respect to surgical outcomes and costs, and discusses early applications of RALUR to complex and reoperative cases. RECENT FINDINGS Intravesical and extravesical techniques for RALUR have been described. Published outcomes vary with respect to operational definitions of surgical success and reporting of complications. Several studies have directly compared RALUR and open reimplant, suggesting equivalent efficacy and safety. Recent noncomparative studies have reported lower VUR resolution rates and higher complication rates for RALUR, particularly in bilateral cases. The application of RALUR to reoperative surgery and cases requiring tapering and dismemberment is under very early investigation. RALUR is consistently associated with lower postoperative analgesic requirements and decreased hospital stay, but longer operative times and higher costs compared to open reimplant. SUMMARY Published outcomes after RALUR show mixed results that, on average, may be inferior to open reimplant. Future investigations should seek to identify patient-related and intraoperative factors associated with successful and unsuccessful outcomes.

Abstract
BACKGROUND Pediatric robot-assisted surgery is increasingly being performed, but it is difficult to perform this procedure in infants. A pediatric thoracoscopic model of a 1-year-old patient was developed in our previous study, and this model was used to evaluate the use of a surgical robot for infant surgery. METHODS Eight pediatric surgeons performed an intracorporeal suturing and knot-tying task using the da Vinci Xi Robotic Surgical System. The task completion time, number of needle manipulations, and force applied during suturing of the robot-assisted thoracoscopic surgery (RATS) group were compared with those of the video-assisted thoracoscopic surgery (VATS) group whose data had been collected from the same 8 surgeons in our previous study. RESULTS The RATS group showed a significantly shorter completion time than the VATS group in the knot-tying phase (P = .016) and in the total phase (P = .0078). The RATS group showed a significantly smaller number of manipulations than the VATS group in the total phase (P = .039). The RATS group showed a significantly smaller pushing force index than the VATS group in the suturing phase (P = .031), knot-tying phase (P = .031), and in the total phase (P = .031). A seventh rib in the model was dislocated in all RATS group cases. CONCLUSIONS The da Vinci Surgical System might be useful in infants because of fast movement and small pushing force. However, the robotic 8 mm instruments were too large for use in the thoracic cavity of the 1-year-old infant.

Abstract
Comparative studies and large-scale case series that confirm the advantages of laparoscopy in children with hepatobiliary diseases are scarce, and the use of laparoscopy remains a matter of debate. This article reviews the current literature on the role of laparoscopic and robotic surgery in pediatric patients with choledochal cyst, biliary atresia, gallbladder diseases, and hepatobiliary malignancies. Studies were identified through a search of the MEDLINE database. Laparoscopy may be beneficial for resection of choledochal cyst and cholecystectomy. However, more data are required before recommendations on the use of minimally invasive techniques for other hepatobiliary conditions can be published.

Abstract
OBJECTIVES To compare the outcomes of robot-assisted heminephrectomy for duplex kidney in children with those of open heminephrectomy. METHODS The present retrospective multicentric analysis reviewed the records of robot-assisted versus open heminephrectomy carried out for duplex kidney in children from 2007 to 2014. Demographic data, weight, surgical time, hospital stay, complications and outcome were recorded. Follow up was based on a clinical review, renal sonography and dimercaptosuccinic acid renal scintigraphy. RESULTS A total of 15 patients underwent robot-assisted heminephrectomy, and 13 patients underwent retroperitoneal heminephrectomy by open approach. All patients weighed <15 kg. The mean age at the time of surgery was 20.2 months (range 7-39 months) in the robotic group, and 18.4 months (range 6-41 months) in the open group. The mean hospital stay was statistically longer for the open surgery group (6.3 days, range 5-8 days vs 3.4 days, range 1-7 days; P < 0.001). Regarding postoperative pain control, total morphine equivalent intake was statistically greater for the open group (0.52 mg/kg/day vs 1.08 mg/kg/day; P < 0.001). No patient lost the remaining healthy moiety. There was no significant difference in terms of operating time, complication rate or renal outcomes. CONCLUSIONS Robot-assisted heminephrectomy in small children seems to offer comparable renal outcomes with those of its standard open surgery counterpart. Specific technical adjustments are necessary, which typically increase the set-up time.

Influence of hospital-level practice patterns on variation in the application of minimally invasive surgery in United States pediatric patients. J Pediatr Surg 2017; 52:1674-1680.

Abstract
BACKGROUND Although disparities in access to minimally invasive surgery are thought to exist in pediatric surgical patients in the United States, hospital-level practice patterns have not been evaluated as a possible contributing factor. METHODS Retrospective cohort study using the Kids' Inpatient Database, 2012. Odds ratios of undergoing a minimally invasive compared to open operation were calculated for six typical pediatric surgical operations after adjustment for multiple patient demographic and hospital-level variables. Further adjustment to the regression model was made by incorporating hospital practice patterns, defined as operation-specific minimally invasive frequency and volume. RESULTS Age was the most significant patient demographic factor affecting application of minimally invasive surgery for all procedures. For several procedures, adjusting for individual hospital practice patterns removed race- and income-based disparities seen in performance of minimally invasive operations. Disparities related to insurance status were not affected by the same adjustment. CONCLUSION Variation in the application of minimally invasive surgery in pediatric surgical patients is primarily influenced by patient age and the type of procedure performed. Perceived disparities in access related to some socioeconomic factors are decreased but not eliminated by accounting for individual hospital practice patterns, suggesting that complex underlying factors influence application of advanced surgical techniques.

Abstract
BACKGROUND A surgical robot offers enhanced precision, visualization, and access and the potential to improve outcomes in cleft palate surgery. The goal of this study was to investigate the feasibility of using the da Vinci robot for cleft palate repair in infants using a cleft palate simulator test bed. METHODS A high-fidelity cleft palate simulator was developed that allows performance of a robotic cleft palate repair procedure. A complete cleft palate repair was performed with the da Vinci Si with 5-mm instruments and the da Vinci Xi with 8-mm instruments. The advantages of the robotic approach were assessed in comparison with using standard instruments. For each system, arm repositioning, collisions, instrument and endoscope excursion, wrist orientation, and vision were compared for 12 steps of the repair. RESULTS The cleft palate simulator provided a reproducible platform for testing robotic cleft palate surgery. The advantages of the robotic approach were the ability to articulate a miniature wrist intraorally with superior visualization, increased ambidexterity, and improved ergonomics compared with using standard instruments. Cleft palate repair with the Xi was superior to the Si with respect to arm repositioning, instrument collisions and excursion, and wrist orientation. However, Xi performance remained suboptimal because of the larger instruments. CONCLUSIONS Robotic cleft palate repair using the da Vinci system offers advantages compared with the traditional approach. Cleft palate repair is more feasible with the Xi and 8-mm instruments. However, performance is limited by the instrumentation, which requires modification to ensure safety and efficacy. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, V.

Abstract
The inaugural robot-assisted urological procedure in a child was performed in 2002. This study aims to catalogue the impact of this technology by utilizing bibliographic data as a surrogate measure for global diffusion activity and to appraise the quality of evidence in this field. A systematic literature search was performed to retrieve all reported cases of paediatric robot-assisted urological surgery published between 2003 and 2016. The status of scientific community acceptance was determined using a newly developed analysis model named progressive scholarly acceptance. A total of 151 publications were identified that reported 3688 procedures in 3372 patients. The most reported procedures were pyeloplasty (n = 1923) and ureteral reimplantation (n = 1120). There were 16 countries and 48 institutions represented in the literature. On average, the total case volume reported in the literature more than doubled each year (mean value increase 236.6% per annum). The level of evidence for original studies remains limited to case reports, case series and retrospective comparative studies. Progressive Scholarly Acceptance charts indicate that robot-assisted techniques for pyeloplasty or ureteral reimplantation are yet to be accepted by the scientific community. Global adoption trends for robotic surgery in paediatric urology have been progressive but remain low volume. Pyeloplasty and ureteral reimplantation are dominant applications. Robot-assisted techniques for these procedures are not supported by high quality evidence at present. Next-generation robots are forecast to be smaller, cheaper, more advanced and customized for paediatric patients. Ongoing critical evaluation must occur simultaneously with expected technology evolution.

Abstract
Developments in pediatric robotic surgery have increased the feasibility of minimally invasive surgery for complex urinary tract reconstruction. Ureteroureterostomy is a commonly employed strategy for the management of a duplicated ureteral system with either upper pole obstruction or lower pole vesicoureteral reflux, and this approach minimizes the risk to a healthy ureter as might be seen in a common sheath ureteral reimplant and avoids complex dissection around the renal hilum as with a heminephrectomy. The robotic platform enables optimum instrument manipulation for an end-to-side ureteral anastomosis as well as excellent visualization deep into the pelvis for excision of the distal ureteral stump. In this study, the indications and preoperative evaluation for pediatric robotic ureteroureterostomy (RUU) were described and intraoperative considerations for a successful repair were highlighted. In order to assess the outcomes, a PubMed search was performed to find the articles focusing on RUU in the pediatric population. The institutional experience of the authors was also reviewed. As with an open procedure, both minimizing dissection on the recipient ureter and ensuring a tension-free, watertight anastomosis are key principles to minimize complications. Although port placement is similar to that in robotic pyeloplasty, small adjustments may need to be made to ensure access to the pelvis. An assistant port and/or traction sutures is often used to aid in the dissection and anastomosis. RUU was first described in 2008, and several reports have demonstrated positive short-term results. However, median follow-up times are limited with most series reporting outcomes <1 year postoperatively. A future study is required to establish the long-term efficacy of this procedure and define the optimum patient population for a robotic approach.

Abstract
The da Vinci robotic system has improved surgeon dexterity, ergonomics, and visualization to allow for a minimally invasive option for complex reconstructive procedures in children. Over the past decade, robot-assisted laparoscopic ureteral reimplantation (RALUR) has become a viable minimally invasive surgical option for pediatric vesicoureteral reflux (VUR). However, higher-than-expected complication rates and suboptimal reflux resolution rates at some centers have also been reported. The heterogeneity of surgical outcomes may arise from the inherent and underestimated complexity of the RALUR procedure that may justify its reclassification as a complex reconstructive procedure and especially for robotic surgeons early in their learning curve. Currently, no consensus exists on the role of RALUR for the surgical management of VUR. High success rates and low major complication rates are the expected norm for the current gold standard surgical option of open ureteral reimplantation. Similar to how robot-assisted laparoscopic surgery has gradually replaced open surgery as the most utilized option for prostatectomy in prostate cancer patients, RALUR may become a higher utilized surgical option in children with VUR if the adoption of standardized surgical techniques that have been associated with optimal outcomes can be adopted during the second decade of RALUR. A future standard of RALUR for children with VUR whose parents seek a minimally invasive surgical option can arise if widespread achievement of high success rates and low major complication rates can be obtained, similar to the replacement of open surgery with robot-assisted laparoscopic radical prostectomy as the new strandard for men with prostate cancer.

Abstract
BACKGROUND Published reports of outcomes of robot assisted laparoscopic ureteral reimplantation (RALUR) show mixed results that, on average, are inferior to open ureteral reimplant. We present a retrospective analysis of a prospective series of children who had RALUR from 2013 to June 2015. We hypothesized that surgical outcomes are based on identifiable risk variables. We provide a critical analysis of the relationship between patient characteristics and several surgical and non-surgical outcomes. METHODS We reviewed the records of children who had Robot-Assisted Laparoscopic (RAL) Ureteral Reimplant (UR) at Nationwide Children's Hospital. Patient age and gender, preoperative presentation, presence of preoperative bladder and bowel dysfunction (BBD), VUR grade and laterality, indication for operation, operative time, surgical outcome, surgical complications, post-operative prevalence of UTI, and pre- and post-operative status of BBD were recorded. We also recorded techniques for ureteral dissection, and closing the detrusorrhaphy. Surgical outcome was defined by post-operative VCUG. We define BBD based on publications by the standardization committee of International Children's Continence Society (ICCS). All statistical calculations were performed with STATA version 11. RESULTS We performed extravesical RALUR on 54 children for a total of 72 ureters. Overall the study children were 74% female. The mean and median age was 5.2 and 4.9 years, respectively. Mean overall hospital length of stay (LOS) was 1.64 days. The mean LOS was 1.26 for unilateral (RALUUR) and 2.39 days for bilateral (RALBUR) surgeries and was significant (p < 0.05). Overall surgical success was 85.2% of ureters and 84.7% of children. Stratified by unilateral and bilateral surgeries, unilateral success was 91.7%, and bilateral success was 77.8% of ureters, and 72.2% of children. In the 3 failures in the RALUUR group the mean postoperative VUR grade was 1.3 from a pre-op mean grade of 3.3, whereas in the RALBUR group, the mean VUR grade among the failures was 3.0 from a mean pre-op VUR grade of 3.7. Urinary leak from ureteral injury, and urinary obstruction were more common in the RALBUR group. Post-operative urinary retention occurred in 4 children in the RALBUR and none in the RALUUR groups. Four with VUR after RALBUR and one child after RALUUR had open ureteral reimplant. Post-op UTI and non-surgical readmissions were higher in the RALBUR group. CONCLUSIONS Bilateral RALUR is associated with higher failure rates, higher complication rates, higher re-operation rates, and more postoperative UTIs and nonsurgical readmissions compared with unilaterasl RALUR.

Abstract
While robotic surgery has shown clear utility and advantages in the adult population, its role in pediatrics remains controversial. Pediatric-sized robotic instruments and equipment are not readily available yet, so certain modifications can be made in order to make robotic surgery successful in children. While the cost of robotic surgery remains high compared to open procedures, patients experience greater satisfaction and quality of life with robotic surgery. Robotic pyeloplasty is a standard of care in older children, and has even been performed in infants and re-do surgery. Other robotic procedures performed in children include heminephroureterectomy, ureteroureterostomy, ureteral reimplantation, urachal cyst excision, bladder diverticulectomy, and bladder reconstructive procedures such as augmentation, appendicovesicostomy, antegrade continence enema, bladder neck reconstruction and sling, as well as other procedures. Robotic surgery has also been used in oncologic cases such as partial nephrectomy and retroperitoneal lymph node dissection. Future improvements in technology with production of pediatric-sized robotic instruments, along with increases in robotic-trained pediatric urologists and surgeon experience along each's learning curve, will help to further advance the field of robotic surgery in pediatric urology.

Open versus minimally invasive ureteroneocystostomy: A population-level analysis. J Pediatr Urol 2016; 12:232.e1-6.

Abstract
INTRODUCTION Open ureteroneocystostomy (UNC) is the gold standard for surgical correction of vesicoureteral reflux (VUR). Beyond single-center reports, there are few published data on outcomes of minimally-invasive (MIS) UNC. Our objective was to compare postoperative outcomes of open and MIS UNC using national, population-level data. METHOD We reviewed the 1998-2012 Nationwide Inpatient Sample to identify pediatric (≤18 years) VUR patients who underwent either open or MIS UNC. Demographics, National Surgical Quality Improvement Program (NSQIP) complications, length of stay (LOS), and cost data were extracted. Statistical analysis was performed using weighted, hierarchical multivariate logistic regression (complications) and negative binomial regression (LOS, cost). RESULTS We identified 780 MIS and 75,976 open UNC admissions. Compared with patients undergoing open UNC, patients who underwent MIS UNC were likely to be older (6.2 versus 4.8 years, p < 0.001), publically insured (43 versus 26%, p < 0.001), and treated in recent years (90 versus 46% after 2005, p < 0.001). MIS admissions were associated with a significantly shorter length of stay (1.0 versus 1.8 days, p < 0.001) and higher cost ($9230 versus $6,304, p = 0.002). After adjusting for patient-level confounders (age, gender, insurance, treatment year, and comorbidity), and hospital-level factors (region, bedsize, and teaching status), MIS UNC was associated with a significantly higher rate of postoperative urinary complications such as UTIs, urinary retention, and renal injury (OR 3.1, p = 0.02), shorter LOS (RR 0.8, p = 0.02), and higher cost (RR 1.4, p = 0.008). DISCUSSION Strengths of this study are its large cohort size, long time horizon, national estimation, and cost data. Most prior studies are case-series limited to the size of the institutional cohort. Our analysis of 76,756 operative encounters revealed that open UNC continues to be performed at far greater frequency than MIS UNC, outpacing the latter modality by nearly 100:1. Children treated with MIS UNC had three times greater odds of developing postoperative urinary complications, and MIS UNC patients incurred average costs per admission that were nearly 1.5 times higher than those of children who underwent open UNC. These children were also likely to be older, publically insured, and treated in more recent years. On the other hand, patients treated with MIS UNC required substantially shorter postoperative hospitalization, with an average LOS roughly half that of open UNC cases. Limitations include the retrospective nature of the administrative database, lack of detailed patient-level data, and no available long-term postoperative outcomes. Compared with open surgery, MIS UNC was associated with shorter LOS but higher costs and possibly higher urinary complication rates.

Abstract
BACKGROUND Laparoscopic Kasai portoenterostomy has been performed in infants with biliary atresia at several institutions, but laparoscopic anastomosis requiring multi-directional suturing on a vertical plane of the liver remains a challenge. To assist multi-directional suturing, we developed a multi-degree-of-freedom (DOF) needle driver whose tip length was 15 mm and shaft diameter was 3.5 mm. The tip of the multi-DOF needle driver has three DOFs for grasp, flection and rotation. The aim of this study was to evaluate the performance of the multi-DOF needle driver in two kinds of in vivo experiments. METHODS Surgeons were asked to perform four-directional laparoscopic suturing on a vertical plane of the liver in six rabbits using the multi-DOF needle driver or a conventional needle driver. The needle grasping time, the needle handling time, the number of needle insertions, the number of liver lacerations, the suturing width and depth, and the area of necrotic tissues were analyzed and compared. Additionally, one surgeon was asked to perform laparoscopic hepato-jejunostomy in four rabbits to assess the feasibility of Kasai portoenterostomy using the multi-DOF needle driver. RESULTS The suturing depth using the multi-DOF needle driver was significantly larger than that using the conventional needle driver in both the right and downward suturing directions. No statistically significant differences were found in other metrics. Liver lacerations were observed only when suturing was performed using the conventional needle driver. The experimental laparoscopic hepato-jejunostomy using the multi-DOF needle driver was successful. CONCLUSIONS Using the multi-DOF needle driver, uniform multi-directional suturing on a vertical plane of the liver could be performed. The short distal tip of the multi-DOF needle driver demonstrated its advantages in multi-directional suturing in a small body cavity. The multi-DOF needle driver may be able to be used to perform complex tasks in laparoscopic Kasai portoenterostomy.
